ABSTRACTBackground: Delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. The aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   Methods: The software was written based on local enhancement of the pixel values in image ma...

Objective: The aim of this study was ultrasonographic findings and technique ofthe liver in the Lori breed sheep.Design: Descriptive study.Animals: 10 clinically healthy, female sheep.Procedures: Ultrasound examination of liver performed from the caudal aspect of13th rib to the 7th intercostals spaces (ICS). The possibility of liver imaging fromeach ICS, distance between the position of liver i...

Background: To retrospectively evaluate whether quantitative information derived from spectral imaging can improve the differential diagnosis of pancreatic cystic masses including pancreatic solid pseudopapillary epithelial neoplasms (SPENs), mucin- producing cysts and pseudocysts. Materials and Methods: From June 2015 to October 2017, 56 patients (22 pseudocysts, 18 mucin-producing cysts and 1...

Portal vein aneurysm is a relatively uncommon entity. It is often an incidental, asymptomatic nding. With the increasing availability of advanced imaging modalities like Doppler ultrasound, computed tomography and magnetic resonance imaging, portal venous system aneurysms are being increasingly reported. We report two cases of intra hepatic portal vein aneurysm diagnosed incidentally on ultra-...

BACKGROUND Hepatic portal venous gas is a rare imaging finding most commonly associated with intestinal ischaemia and high mortality. Increased use of advanced imaging techniques has resulted in increased reporting and recognition of hepatic portal venous gas. Advanced imaging can also recognise the many associated pathologies which have variable management strategies and prognoses. METHODS W...

A 64-year-male underwent a liver biopsy based on clinical concern for primary biliary cirrhosis. The biopsy, which yielded normal results, was uneventful, with no immediate postbiopsy complications. A later MRI demonstrated early opacification of the right portal vein on arterial-phase imaging, suggesting communication between the right hepatic artery and the right portal vein. A conservative, ...
